Abstract (en)
Provided are a liner structure and a blow-molding manufacturing method for a liner structure. The liner structure includes a liner main body and an insert located inside an opening of the liner main body. The liner main body is made of a polybutylene material. According to the liner structure and the manufacturing method thereof, the liner structure has relatively good heat resistance within a temperature range corresponding to conventional liquid water, and can be used for containing hot water. Moreover, a feasible manufacturing method is provided. The method can overcome defects of material characteristics through process optimization, so that can implement manufacturing the liner structure.
